Abstract

The methods for ensuring long-term and safe operation of marine equipment due to comprehensive repair technologies that use epoxy oligomers and new compositions based on them are developed. The influence of temperature and UltraSonic Treatment (UST) on the rheological properties of the pure epoxy matrix and compositions based on it is explored. The compositions have different content of nanodispersed soot carbon black of brand PowCarbon 2419G (particle size of 24 ± 2 nm). It is established that when nanoparticle soot (q = 0.10…15.00 pts wt) is introduced into the composition of the epoxy matrix treated with ultrasound, the viscosity of the composition increases gradually. Based on the results obtained, temperature ranges are recommended, in which the viscosity of the studied compositions reaches optimal technological parameters for the effective impregnation of threads, tows and various fabrics, and which provide for the effective application of the composition to the working surfaces of marine equipment. Technical recommendations are given for applying the developed black-filled epoxy compositions to the working surfaces of parts, ship mechanisms and pipeline systems of marine vessels.

船用设备表面修补用新型补黑环氧涂料

利用环氧低聚物及其新组合物的综合维修技术，开发了确保船舶设备长期安全运行的方法。探讨了温度和超声处理对纯环氧基及其复合材料流变性能的影响。该组合物含有不同含量的PowCarbon 2419G牌纳米分散烟尘炭黑(粒径为24±2 nm)。结果表明，在超声处理的环氧基复合材料中加入纳米颗粒烟灰(q = 0.10 ~ 15.00 pts wt)后，复合材料的粘度逐渐增大。根据所得结果，推荐了所研究组合物的粘度达到最佳工艺参数的温度范围，以有效浸渍线、拖带和各种织物，并为组合物在船舶设备工作表面的有效应用提供了条件。提出了将所研制的黑填充环氧树脂组合物应用于船舶零件、船舶机构和管道系统工作表面的技术建议。

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
